Software updates for coxeter and sphere at 4:15pm on Wednesday September 25, 2013

The main departmental servers coxeter and sphere will have software updates applied this Wednesday afternoon, September 25, 2013 which will require rebooting.  Since some updates will be applied while these servers are still up there may be some temporary issues with some software. We hope that any such issues will be minor and by doing most of the upgrading before bringing these  systems down the shorter downtime will be worth the potential minor problems. Please restart any programs if you observe problems during the upgrades (and please let us know at, so we can investigate). We expect the systems to be back up by about 5:00pm.
